Sci-Tech Library Newsletter

If you are not already receiving the NSF Library Newsletter by e-mail, and would like to, contact
Stephanie Bianchi. PLEASE STATE WHETHER YOU PREFER THE FULL NEWSLETTER OR JUST THE TABLE OF CONTENTS.

This is a special holiday edition of the Sci-Tech Library Newsletter. I have dusted
this off from last year, repaired the old links, and added a few new ones. Enjoy!

There are lots of holiday sites on the WWW, but you’ll find more than just Santa here.
These sites were chosen for your enjoyment and are of special interest to the sciences
and social sciences, but still, I hope, reflect some of the joys of the season!

E-MAIL A HOLIDAY POSTCARD

There are lots of sites that allow you to send a traditional holiday postcard to your friends,
but NASA provides a site that has lovely postcards with an astronomical theme — for example,
a picture of the earth taken from space and presented as a Christmas tree ball! Add your own
personal message and enjoy! Visit the
Observatorium.

NORTHERN LIGHTS ABLAZE ON YOUR COMPUTER

For gorgeous photographs of this phenomenon, from both the earth and from space, and for a
quick-time movie showing the shimmer, check this site from San Francisco’s famous
Exploratorium Museum (http://www.exploratorium.edu/learning_studio/auroras/).

THE NORTH POLE

The Arctic continues to be a place of important scientific interest. Follow the
1999 NASA expedition to the North Pole.
The expedition’s primary goals were to field test satellite i.p. communication tools — in
a realistic environment, where nothing as good exists, and to collect some meaningful scientific
measurements at the same time. But the website presents much, much more including wonderful
graphics.

The
Houghton Mars Project (http://www.arctic-mars.org/)
isn’t quite at the North Pole, but it’s pretty close … The project is set up to test the
equipment and technology (habitation, transportation, life support, recycling, etc.), that may
be deployed during a human mission to Mars.

Or check the discussions of the various exploration expeditions of the Arctic and
introductions to the indigenous peoples of the Arctic around the world on the
Arctic Circle (http://arcticcircle.uconn.edu/HistoryCulture/)
page.

Greenland is close enough to the North Pole to count as possible Santa-land in my book! You
can get a fabulous free
Yupik Mask Screensaver (http://www.greenland-guide.gl/masks/default.htm).

REINDEER AND THEIR COUSINS

What would the holiday be without reindeer? Or at least their close cousins, the caribou. The
160,000 animals that make up the Porcupine Caribou Herd range throughout the Northern Yukon and
neighbouring Alaska and Northwest Territories. What are the effects of global climate change on
the herd? How do they distribute themselves within their range? What is the influence of snow
density, wind, and insect harrassment on them? Such knowledge is essential in building computer
models to predict the impact of climate change in the caribou population. Enjoy the gorgeous
Slide Show (http://www.taiga.net/caribou/pch/slides/index.html).

At the University of Alaska Reindeer Research Program you can help the staff
choose names (http://reindeer.salrm.uaf.edu/educational_outreach/reindeer/)
for their baby reindeer.

For more information on these lovely animals, go to the fact-filled
Reindeer FAQ (http://reindeer.salrm.uaf.edu/about_reindeer/)
and the
Caribou FAQ (http://alaska.fws.gov/nwr/arctic/caribou.htm).

YULE CAT

Of course there are other animals associated with the holiday season as well, bound by myths
and folktales and cultural traditions. For instance, “from Iceland comes the legend of the
sinister and gargantuan
Yule Cat (http://www.simnet.is/gardarj/yule11.htm),
who, it seems, is ready to eat lazy humans. Those who did not help their village to finish all
work on the autumn wool by Yule time got a double whammy — they missed out on the Yule
reward of a new article of clothing, and they were threatened with becoming sacrifices for the
dreaded Yule Cat”. Read about the
origins of Yule, Saturnalia, and Solstice celebrations (http://www.candlegrove.com/).
or about winter festivals from around the world
to get an understanding of the ways different societies have celebrated these holidays.

THE HOLLY AND THE IVY (AND THE MISTLETOE)

What would the season be without wreaths and garlands? This site at
Texas A&M (http://botany.csdl.tamu.edu/FLORA/gallery.htm)
has gorgeous botanical images — full plant, leaves, flowers, etc. Do a search on Ilex,
Hedera, or Loranthaceae.

THE STAR OF BETHLEHEM

Many planetariums present shows on the Star of Bethlehem at this season, but no matter how hard
you try to be careful and well-researched, errors can creep into the presentation. Find out what
some of the common errors are in the
article (http://www.ips-planetarium.org/planetarian/articles/common_errors_xmas.html)
by John Mosely, program director at the Griffith Observatory.
Griffith Observatory also offers a good list
of authoritative Star of Bethlehem web resources.

You may not expect something as spectacular as the Star of Bethlehem this year, but to keep track
of what you might see in the holiday night sky, check out the weekly report of the
Star Gazer (http://www.jackstargazer.com/),
whom you may have heard on various NPR stations. I hear there will be a spectacular, once-in-a-century
December full moon …

FOR THE SCROOGES AMONG US

But if there is no Santa, how can the sophisticated electronics at
NORAD (http://www.noradsanta.org/)
successfully track the sleigh progress each year?

WILL THERE BE A WHITE CHRISTMAS THIS YEAR?

The
National Climatic Data Center (http://www.stormfax.com/whtexmas.htm)
brings you a region-by-region examination of the climatological chances for a white Christmas in
the continental United States.

(Only 13% chance for Washington, DC. Sigh.)

What does snow really look like, anyway? Check out the fascinating
electron microscope images of snow crystals (http://emu.arsusda.gov/snowsite/default.html),
or join the fun by
making your own snowflake images (http://www.microscopy-uk.org.uk/mag/artfeb00/eksnow.html)
(if you have a microscope handy) using these instructions. (NOTE: When I checked this link, the page
was down for maintenance. Hopefully it will be up again soon).

More links to
snow resources (http://nsidc.org/snow/links.html)
are available from the National Snow and Ice Data Center World Data Center-A for Glaciology.

WHEN IS WINTER, ANYWAY?

For the
exact time of the winter solstice (http://scienceworld.wolfram.com/astronomy/WinterSolstice.html)
for any year between 1992 and 2000, check the chart provided by Wolfram.

The exact time of Solstice was very important to many ancient peoples, who built architectural
structures and developed other sophisticated ways to measure it. Take a tour of Ireland’s
Newgrange passage tomb (http://www.knowth.com/newgrange.htm).
For more information on archaeoastronomy, visit the
Archaeoastronomy Center at the University of Maryland (http://terpconnect.umd.edu/~tlaloc/archastro/cfaar_as.html).

HOLIDAY FUN FOR LINGUISTS

The Linguists among us will enjoy a discussion of the 15 ways
Hannukkah can be transliterated into English.

THE CHEMISTRY OF CHRISTMAS

Ever wonder what the “smell of Christmas” might look like? Check out the
“Swedish Christmas Chemistry”
site. You will find chemical formulas for compounds and processes in spices, lutefisk (I hear its
yummy!), Christmas trees, candlelight, sparklers, and glogg (spiced wine). If you want more
information on these chemical structures, check them out in CS Chemfinder.
You can search by name or chemical structure (and more) to find detailed structure, melting points,
boiling points, specific gravity, and more!

MORE TRADITIONAL SITES:

For fuller coverage of Internet sites on Christmas, Hannukah, Kwanzaa, Ramadan, and the other holidays
we all enjoy, go to the
Yahoo “Holidays and Observances” site (http://dir.yahoo.com/Society_and_Culture/Holidays_and_Observances/)
